Hess's Law states that the total enthalpy change for a reaction is the sum of the enthalpy changes for the individual steps of the reaction, regardless of the pathway taken. This principle can be applied to Gibbs Free Energy calculations, allowing us to combine the ΔG°rxn values of known reactions to find the ΔG°rxn for a target reaction.

Calcium Carbonate = Calcium Oxide + Carbon Dioxide. CaCO3 = CaO + CO2 is a Decomposition reaction where one mole of Calcium Carbonate [CaCO 3] decomposes into one mole of Calcium Oxide [CaO] and one mole of Carbon Dioxide [CO 2]

Δ G rxn = Δ G products − Δ G reactants Step 1: Identify Gibbs Free Energies. From the question, we have the following values: Δ G f , CaCO 3 = − 1128.76 kJ/mol; Δ G f , CaO = − 604.17 kJ/mol; Δ G f , CO 2 = − 394.4 kJ/mol; Step 2: Calculate Δ G rxn Now we can substitute these values into the formula: Δ G rxn = (Δ G CaO + Δ G ...

Calcium Carbonate + Phosphoric Acid = Tricalcium Phosphate + Water + Carbon Dioxide. Three moles of Calcium Carbonate [CaCO 3] and two moles of Phosphoric Acid [H 3 PO 4] react to form one mole of Tricalcium Phosphate [Ca 3 (PO 4) 2], three moles of Water [H 2 O] and three moles of Carbon Dioxide [CO 2]

2023年8月24日 · The calculated ΔG°rxn for the reaction is -472.2 kJ. Explanation: To calculate ΔG°rxn for the given reaction: CaCO3 (s) -> CaO (s) + CO2 (g), we should first reverse the first reaction and add to the second reaction. Therefore, -(-734.4 kJ) = +734.4 kJ (reverse reaction), and second reaction stays the same, -1206.6 kJ.
